How to fix “No Bootable device found” on Windows 10

There are two main probable causes when you encounter this issue. These can be fixed with solutions which we detail below. You’ll also find general troubleshooting tips that may help you in restoring your device.

Method 1. Set your hard drive as the boot device.

Your hard drive may not be set as your first boot device in the BIOS. It should be the default unless you have specifically chosen to boot from a different device. Here’s how we can fix this issue:

  • Restart the computer and tap Esc to enter the BIOS interface.
  • Press the right arrow key on your keyboard until the Boot tab is opened. Move “Hard Drive” to the top of the boot order list by pressing “+” or “-”.
  • Press F10 to save the changes and restart the computer.

Method 2. Remove and connect back all hardware components.

At first, you can completely power off your computer, remove all hardware devices, then put them back all properly. That can help check whether the BIOS did not detect the system hard drive due to lose connection and led to “no bootable device” issue. If this does not work for your situation, proceed to the next method.

Method 3. Fix corrupted MBR.

If the MBR (Master Boot Record) of your system drive gets corrupted, it can cause the “No boot device available” error in Windows 10. This is usually one of the main causes for this problem, and it can be fixed with a few easy steps. Here’s what you need to do to fix your device’s corrupt MBR:

  • Insert the Windows installation media into your computer and boot.

Step 1:

Enter BIOS by pressing the relevant key (F12, DEL, etc) after the restart.

Step 2:
